true
false
2-Principal stresses are the maximum and minimum normal stresses occurring within a loaded member at a selected point.
true
false
3-The maximum shear stresses occur in an element inclined at 45 degrees from the principal axes.
true
false
4-An accurate Mohr’s circle can never be centered at the (0,0) point on the shear (Tau) and normal stress (Sigma) axes.
true
false
5-When constructing Mohr’s circles, it is common to convert all compression normal stresses to tension normal stresses before plotting them.
true
false
